11th of November is both PLAAF anniversary as well as the most well known online shopping festival in China.

Memes aside, their details about J-10(B or C, I can't tell from below) lists something interesting:View attachment 79530
间歇性超音速巡航, or "intermittent supercruise".
Should we be taking this statement seriously?

We can safely take that seriously. Super-cruising of (Chinese designation) 3rd gen jet under certain conditions (outlined by siege) is nothing new nor surprising. We had long debate in this forum. The point is that super-cruising has more to do with fine aerodynamic shaping and drag reduction by eliminating external payload, much less to do with engine thrust which affects acceleration more than top speed. The thrust for maintaining the top speed is pretty small if the drag is small.

Mainly, shaping limits not withstanding, supercruising without using ABs to accelerate into the supersonic regime is about having enough dry thrust to punch through the transonic barrier, which actually has higher drag than at low supersonic speeds.

They say that even for Eurofighter&Raptor it's actually more fuel efficient to just burn through the mach barrier.
For most other "advertised supercruisers", however - it's essentially unfeasible and holds so little practical value that it can be safely ignored. More of an indicator of their good subsonic/transsonic performance than anything else.

But is this really a recent image? ... and even more, I regret, there is no twin-seater based on the J-10C!

... and the most interesting point, still running on AL-31FN. But we haven't heard for any new Sino-Russian AL-31F and FN contract since years, but still they build J-10AS and J-15s at SAC which are using Russian engines.

I think this is a WS-10 not AL-31.

The zooming blades of the exhaust nozzle of AL-31 is much longer than that of WS-10.

How come the fishers so calm witnessing a jetplane crushed on river bank not more than hundreds of meters away from them?

There was an old Chinese saying: 钓鱼佬永不空军！(The fishers will never join the Air Force!)

Give me a 'like' if you know what this means.

I heard that the Pak's J-10CEs were confirmed, and the producing is underway. This is the first time the exact message from China side. If true, we won't wait too long to see these birds.

also saw these:

I'm pretty sure that's an AL-31.

Here's WS-10 for comparison. The nozzle stops quite a bit short of the tail cone:

100% for sure an AL-31FN ... there is no - a least not yet - WS-10-powered J-10AS.
